This is the main stack...
Note how it is offset from the foundation wall. Also that it interfered with the joists (all the branchings from the stack are done at same height as the hoists)
Note how there are NO JOISTS underneath either of these bathrooms. The stack continues straight up, and is "in" the wall above it. That wall separates two bathrooms. Both bathrooms are being redone. The one at right will be done now. The one at left will be done later.
(seen branching out left & right of the stack are the connects to the toilets in each bathroom; seen extending "away" from the wall are the pvc to the left bathroom's shower and the right bathroom's sink; seen extending "into" the wall is the pvc for the right bathroom's tub and the left bathroom's sink...the next 2 pictures shows the pvc "into" the wall, and the right bathroom's stack & connects on the ground floor)
I need to replace the subflooring in BOTH bathrooms, but as I said, I need to do them separately. That is why there is a problem with NO JOISTS underneath: it is all one subfloor.
I have a friend who says he can jack support the left bathroom's floor, and, coupled with adding whatever joist support he can add, proceed to subflooring only the right bathroom . Then we'd tile walls & floors and fixturize that one. Once the right bathroom is completed, we'd go back later & redo the left bathroom.
He mentioned it would be a WHOLE LOT EASIER if the branching from the stack were done below the joists. That would mean redoing the stack to lower the branchouts below the joists.
What would you expect a plumber's cost to be to have that stack redone to branch below the joists? $500? 5,000?? Gimme a ballpark for labor & materials.
I'm considering doing it myself. For a virgin pvc DIY'er, am I looking for trouble? How long do you think it'd take?
Finally, what would YOU do? Jack & joist & leave the stack alone, or redo stack and then jack & joist?
Thanks!
